Arsenal's failure to sign a prolific striker might have cost the team the chance to win the Premier League title.

Frequently collecting red cards hasn't helped, either.

Second-placed Arsenal was unexpectedly beaten 1-0 at home by West Ham on Saturday to dent its title challenge, just when it seemed Liverpool was starting to look vulnerable.

The result left Liverpool with an eight-point lead, having played the same number of games as Arsenal.

Jarrod Bowen's 44th-minute header secured a win for West Ham, which arrived at Emirates Stadium with just one victory in its last eight games. There was worse to come for Arsenal, with left back Myles Lewis-Skelly handed a red card in the 73rd, following a video review for his foul on Mohammed Kudus as the last man.

It was Arsenal's fifth red card of the campaign — two more than any other team — and its disciplinary record under Mikel Arteta is understandably coming under scrutiny, given it has contributed to valuable dropped points this season.

Maybe a bigger annoyance to fans is the club's decision to not sign a proven out-and-out striker, either in the offseason or in the winter transfer window.

With forwards Kai Havertz, Bukayo Saka, Gabriel Martinelli and Gabriel Jesus all out injured, Arsenal had only two shots on target against the Hammers.

"I am very disappointed, and obviously very angry as well," Arsenal manager Arteta said. "Even though we had 20 shots, I never felt that we were at the standard and the level that we needed.

"We have to be (angry), and I hope we are, because we didn't hit the levels today, and I am very much responsible for that.

"We never got a grip of it. We didn't generate a threat or any momentum," Arteta added.

"It is painful, but this is sport. We need to feel the pain today, I think we deserve that."

Second half rally

Manchester United came from two goals down before benefiting from a last-gasp video-review call to draw 2-2 at Everton.

Uruguay midfielder Manuel Ugarte grabbed the 80th-minute equalizer for United with his first goal at club level in four years, eight minutes after Bruno Fernandes started the visitor's fightback at Goodison Park by curling in a freekick.

United had been on course to slip to a third straight loss — and ninth defeat in 15 league matches since Ruben Amorim took charge in November — after first-half goals by Beto and Abdoulaye Doucoure for David Moyes' resurgent Everton.

There was a late scare for United when Everton was awarded a penalty for what appeared to be a foul by Harry Maguire on Ashley Young, who fell to the ground dramatically under pressure from Maguire and Matthijs de Ligt in the third minute of stoppage time.

Following a video review, on-field referee Andrew Madley was advised to review the incident on the pitch-side monitor and he changed his initial decision.

Moyes was, understandably, annoyed, saying afterward: "I just thought the referee made the correct decision at the time, and should have stuck with it."

Amorim said United "just played one half and we managed to draw the game".

"We didn't exist in the first half," he lamented.

Keeper woes continue

A huge late mistake from Chelsea goalkeeper Filip Jorgensen proved costly, as Aston Villa came from behind to win 2-1 in a match between two teams chasing Champions League qualification.

Jorgensen, only playing after a number of recent errors by first-choice keeper Robert Sanchez, somehow let a shot from Marco Asensio squirm out of his grasp and over the line in the 89th minute at Villa Park.

That was Asensio's second goal of the game. He scored the equalizer in the 57th — canceling out Enzo Fernandez's ninth-minute goal that put Chelsea in front — after being set up by fellow new signing Marcus Rashford, who also provided the cross for the winner.

Villa climbed to seventh, a point and a place behind Chelsea with England almost guaranteed to be getting five qualification places for next season's Champions League.

Bournemouth slips up

Fifth-placed Bournemouth, which is on the same points as Chelsea, lost 1-0 at home to Wolverhampton, damaging its bid for Champions League qualification.

Bournemouth defender Illia Zabarnyi's 31st-minute red card was quickly followed by the winning goal by Matheus Cunha for Wolves.

Tottenham beat Ipswich 4-1 for a third straight league win, further easing pressure on manager Ange Postecoglou, last-placed Southampton lost 4-0 at home to Brighton, and Crystal Palace won 2-0 at Fulham.
